The Mets (18-15) and Yankees (16-17) have played 33 games, which is approximately 1/5 of the way into the season. Each team has produced more questions than answers. Either could win the World Series or finish third or worse in their division, and I don’t think anyone would be stunned.

Omir Santos, catcher: B+ — Nothing spectacular, but for someone no Mets fan had heard of before the season, you’ll take a .277 average and a decent throwing arm. Brian Schneider finally returning from his injury could be the worst thing for the Mets; they seem committed to giving Schneider back the starting job when he comes off the disabled list.

Carlos Delgado, first base: B- — If we are comparing this to his start last year then you should be thrilled. Does he have a run when he puts the team on his back like he did last year? Let’s hope so, but that won’t come until after a DL trip for his ailing hip, which will likely begin Friday.

Luis Castillo, second base: A- — Everyone’s favorite punching bag is off to a nice start. The fact Jerry Manuel used him as a pinch hitter in a clutch situation Tuesday night is all you need to know. And he actually came through with a game-tying sacrifice fly. Last year he would have been the one being pitch hit for.

Jose Reyes, shortstop: C+ — Same ability to excite any time he steps up to the plate. Also, same ability to make you put your foot through the television with base-running blunders.

David Wright, third base: C- — Three home runs and still struggling in big situations.

Daniel Murphy, left field: B- — The hitting has been what we hoped. The fielding has been what we feared — just ask Johan Santana.

Carlos Beltran, center field: A — Remember when the Mets signed Beltran after he went bonkers in the playoffs for the Astros? That’s how he has played at the start of this season. MVP-type stuff.

Ryan Church, right field: C+ — Good enough start (.313 in April) to keep his starting job, but bad enough afterward (.161 in May) where he’s still looking over his shoulder at Gary Sheffield and Fernando Tatis.

The bench: B — So I am Fernando Tatis and I was the Most Improved Player in the league last year, with the plaque to prove it, the team re-signed me and I am off to a solid start. So where are the at-bats? Fifty-three of them in 33 games is not enough.

Gary Sheffield has had a couple of clutch home runs, but not much beyond that. He could have helped his cause by not striking out looking to end yesterday’s game. As long as he is playing well with others, his spot should be safe.

Ramon Castro and Alex Cora have been solid when called into action.

Johan Santana, starting pitcher: A — He’s the best in baseball right now. And he kept his team from falling into a deep funk when the rest of the starting pitchers were stinking it up.

Mike Pelfrey, starting pitcher: B- — This is a tough one. He seems to have turned a corner after struggling with arm tendinitis early in the season. Concerning stat: He didn’t have a single swing and a miss during a seven-inning start against the Phillies. He did whiff three Braves in his next appearance. But still the Moneyball crowd would not be happy. (Speaking of “Moneyball,” Brad Pitt is starring in the film version. Of all the books I have read in my life, I thought this was the least likely to ever be made into a movie.)

Oliver Perez, starting pitcher: F — I don’t think we need to delve into why; Mets fans have lost enough hair because of this guy already. Let’s just say that at least for now the Wilpon’s investment in Oliver Perez seems equal to the investment they gave Bernie Madoff.

John Maine, starting pitcher: B — If the Mets were starting a playoff series right now Maine would be the guy I’d want starting Game 2. He’s won three straight starts after opening 0-2, some of which I would attribute to coming back from offseason shoulder surgery.

Livan Hernandez, starting pitcher: B — Before the season someone asked me what Hernandez’s numbers would be after six starts and I actually said 3-1 with a 5.08 ERA.

Francisco Rodriguez, closer: A — He is 9-for-9 in save opportunities. K-Rod does give you a good scare sometimes, but always seems to come through when things get real sticky. Interesting note: Billy Wagner would have been given an A at this time last year, too.

J.J. Putz, set-up man: C — The role is a thankless one. Your good performances are expected, and your bad ones are highlighted. Unfortunately there have been too many highlights for Putz this season. The former Mariners’ closer told SNY’s Kevin Burkhardt he is still adjusting to his new role. That excuse will fall on deaf ears with more performances like yesterday’s.

Rest of bullpen: C+ — Sean Green is reminding too many fans of last season. Bobby Parnell has been a beast. Brian Stokes has been great when he gets a chance.

Memo to Manuel: Pedro Feliciano should face only lefties. My friend Eddie, a big-time Mets fan, shut the game off after the manager left Feliciano in to face Atlanta’s Matt Diaz with the bases loaded Monday night. Diaz, who hits righty if you didn’t follow, broke the tie with a two-run single.

Jerry Manuel, manager: C- — People seem to like this guy. His outgoing demeanor is a welcomed switch from gruff Willie Randolph, but he makes some puzzling decisions (see Feliciano above). And he will ultimately be judged by wins and losses, just like Randolph.
